Problems solved by technology

[0004] In the prior art, there are still many defects in the setting technology of vacuum glass supports: 1) In terms of materials, metal materials with good toughness are often used to make vacuum glass supports, but due to the opacity of metal materials, the thermal conductivity is high and the coefficient of thermal expansion is large , which directly affects the performance of the vacuum glass; 2) in the setting, the method of manual placement is usually used: the operator uses tweezers in front of the stage to pick up the support and place it on the surface of the vacuum glass lower sheet; this method is labor-intensive, The speed is slow, the efficiency is low, and it is easy to rework; the phenomenon of misplacing, missing, and placing more supports occurs from time to time
This method increases large-scale vacuum equipment, prolongs the process cycle, and increases the manufacturing cost of the product

Embodiment 1

[0036] Example 1. refer to figure 1 , figure 2 . A method for producing vacuum glass. Put low-melting glass frit paste on one of the glasses to form a glass frit pile 2, and apply a closed strip along the periphery of the glass surface on which the frit pile 2 is placed. Low-melting point glass powder paste strips, with several fortified adhesive supports between the upper and lower glass pieces, put the pieces together and heat-melt them in the sintering furnace. While heat-melting and sealing the edges, the glass powder pile 2 is melted to form a glass The support 1 is vacuum-sealed to obtain vacuum glass.

Embodiment 2

[0037] Example 2. refer to figure 1 , figure 2 . A method for producing vacuum glass, in which low-melting point glass frit paste is placed on one piece of glass by dripping to form a pile of glass frit 2, and the glass surface on which the frit pile 2 is placed is placed along the periphery of the glass surface. Apply a closed strip of low-melting glass powder paste, and set several fortified adhesive supports between the upper and lower sheets of glass. After the sheets are combined, they are placed in a sintering furnace for heat fusion. 2 The glass support 1 is formed after melting, and the vacuum glass is obtained after vacuum sealing. The vacuuming method is to drill a straight hole for exhaust on the upper piece of glass, place a non-evaporable getter in the hole, then insert the exhaust glass tube, and coat the glass surface around the glass tube with low The melting point glass powder paste is melted in the sintering furnace, then heat-preserved, cooled to the ex...

Abstract

The present invention relates to a production method of vacuum glass. It is characterized by that said method includes the following steps: point-placing glass powder slurry with low-melting point on one glass sheet surface so as to form glass powder piles, coating a closed low-melting-point glass powder strip along four edges of the glass sheet, setting several anti-adhesive supports between upper and lower glass sheets, combining two glass sheets, placing them into sintering furnace to make hot-melting, at the same time of hot-melting and sealing edge the glass powder piles are molten so as to form glass supports, evacuating and sealing so as to obtain the invented vacuum glass.

Description

technical field [0001] The invention relates to a method for producing glass, in particular to a method for producing vacuum glass. technical background [0002] In modern buildings, glass has been widely used. Double-layer hollow glass is now popularly used as door, window and wall glass. The main technical indicators, sound insulation and heat insulation performance are better than single-layer glass. However, compared with insulating glass, the sound insulation and heat insulation performance of vacuum glass is better. The heat flow rate of single-layer vacuum glass is 1.0kcal / m 2 hr℃, while the heat penetration rate of insulating glass is as high as 3.0kcal / m 2 above hr℃. The heat penetration rate with the wall is 0.3~0.5kcal / m 2 Compared with hr℃, multi-layer and composite vacuum glass can be used in buildings, which is particularly important for the sound insulation and heat resistance of buildings. [0003] The production method of v...
